This sea pool is at the South end of Coogee Beach Sydney.
It is lit from flood flights from 20 meters above at street level and from the Surf Club building.
I took the photos on a misty overcast night and at low tide, luckily very little sea breeze. I have seen exposures take here where the sky was also lit...Probably with a low cloudbase but clear skys below so the city light could reflect.I also had great difficulty composing shots of the pool its self.I came to the conclusion that the best way would be standing waist deep in the pool with the tripod... another night maybe. I will post the best and you decide where you would have framed the shot.
3 minutes F10 11mm Sigma wide using a ND8 (3 stops dark ) filter.ISO100 of course.
